    fixincludes: Update darwin_flt_eval_method for macOS 14
    
    On macOS 14, a guard in <math.h> changed:
    
    -- MacOSX13.3.sdk/usr/include/math.h    2023-04-19 01:54:44

    Therefore the darwin_flt_eval_method fixincludes fix doesn't match any
    longer, leading to a large number of testsuite failures like
    
    /private/var/gcc/regression/master/14-gcc/build/gcc/include-fixed/math.h:69:5:
    error: #error "Unsupported value of __FLT_EVAL_METHOD__."
    
    where __FLT_EVAL_METHOD__ = 16.
    
    This patch adjusts the fix to allow for both forms.
    
    Tested with make check in fixincludes on x86_64-apple-darwin23.0.0 and
    verifying that <math.h> has indeed been fixed as expected.

            fixincludes:
            * inclhack.def (darwin_flt_eval_method): Handle macOS 14 guard
            variant.
            * fixincl.x: Regenerate.
            * tests/base/math.h [DARWIN_FLT_EVAL_METHOD_CHECK]: Update test.
    
    (cherry picked from commit 93f803d53b5ccaabded9d7b4512b54da81c1c616)
